due to limited stock in TCSS AND the fact i had amazon gift card balance i bought my speaker for my project from amazon. i specifically looked for the 28mm sized ones to fit in the hilt and well. technically they are 28mm. however.
dremal foo is needed to extract them because the blocks they come in ARE the speakers. not just some fancy housing to make mounting "easier" for whatever project.



here is a link to the speakers if you want to avoid them and just buy ones that are rounded and ready to use out of the box.

if i would of known. i would of payed the extra $2 for the top of the line single speaker from TCSS.


side note. i tried them on a small bluetooth amp (i plan to make a BT speaker) and they sound horrible! ALL mid. no trebble or bass!
